The Earth's layers of atmosphere differ in chemical composition and temperature. They combine to create a protective sheild that maintains our delicate energy balance essential for life on Earth. Most weather occures in the nearest layer, the troposphere (0-7 miles). The stratosphere is the level where jet airliners fly and the ozone layer resides (7-30 miles). Beyond that is the coldest part of the atmosphere, the mesosphere where only large helium balloons fly (30-50 miles). Finally, the...

Deep Water Feast: Upwellings Bring Nutrients to The Surface- Large phytoplankton blooms tend to coincide with natural phenomena that drive cold, nutrient-rich water to the surface. The process is called upwelling. Here's what's happening: winds coming off principal land masses push surface layers of water away from the shore. Into the resulting wind-driven void deeper water underneath the surface layers rushes in toward the coast, bringing with it nutrients for life to bloom. It's different on...

The 'greenhouse effect' is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the 'greenhouse,' but blocking Earth's heat from escaping into space. The gases that contribute to the greenhouse effect include water vapor, carbon dioxide (CO2), methane, nitrous oxides, and chlorofluorocarbons (CFCs). On Earth, human activities are changing the natural...

The Carbon Cycle - The carbon cycle on land, acted out here show a tree taking in carbon dioxide from the atmosphere, and combined with water and nutrients from the soil, growing. In the fall and winter, parts of the growth die off and release some carbon back into the system. At some point, the tree is no longer able to take in carbon and begins to die. When that happens, all the carbon absorbed in its body is released back into the cycle as it decomposes. Fire can accelerate this, sending...

Carbon is the root of all life on Earth, and as it circulates through our biosphere, the Earth's state of health responds. Whenever the size of phytoplankton colonies in the ocean changes, it affects the amount of carbon absorbed from the atmosphere. These blooms are highly dependent on surrounding environmental conditions. As a hurricane passes over the tropical waters of the Atlantic, it draws up cold water from deep below the warmer surface. As the cooler water rises, it brings with it...

Abnormal sea surface temperatures (SST) in the Pacific and the Atlantic Ocean played a strong role in the 1930s dust bowl drought. Scientists used SST data acquired from old ship records to create starting conditions for the computer models. They let the model run on its own, driven only by the observed monthly global sea surface temperatures. The model was able to reconstruct the Dust Bowl drought quite closely, providing strong evidence that the Great Plains dry spell originated with abnormal...

As part of the ocean conveyor belt, warm water from the tropical Atlantic moves poleward near the surface where it gives up some of its heat to the atmosphere. This process partially moderates the cold temperatures at higher latitudes. As the warm water gives up its heat it becomes more dense and sinks. This circulation loop is closed as the cooled water makes its way slowly back toward the tropics at lower depths in the ocean. If the poles warm, it is possible that melt water from glaciers and...

Normal rainfall droplet creation involves water vapor condensing on particles in clouds. The droplets eventually coalesce together to form drops large enough to fall to Earth. However, as more and more pollution particles (aerosols) enter a rain cloud, the same amount of water becomes spread out. These smaller water droplets float with the air and are prevented from coalescing and growing large enough for a raindrop. Thus, the cloud yields less rainfall over the course of its liftime compared...

Like clouds in other parts of the atmosphere, one element required for polar mesospheric clouds to form is tiny dust particles on which water vapor can accumulate and grow into ice crystals. Nearer to Earth's surface, clouds form from 'cloud condensation nuclei' that can be sea salt spray, desert dust, or other materials lofted from the surface. In the mesosphere it is thought that cosmic dust particles falling into the Earth's atmosphere might serve this same purpose, and the Cosmic Dust...

The Water Cycle - Water falling from summer storm clouds onto a field of wheat today will someday fall again somewhere else. This is the essence of the water cycle.

Vapor leaves plants through tiny pores called stomata. This process is called transpiration. As moist air ascends into the atmosphere...

Methane is a simple compound made of carbon and hydroge. This gas comes from ordinary sources, like cattle herds and garbage dumps. On a planetary scale it also has a significant impact on climate. As it builds up in the atmosphere, it traps energy from the sun like a layer of insulation. Carbon dioxide does much the same thing-it causes global warming by trapping heat. But as experts struggle to curtail global climate change, a decrease of atmospheric methane might be easier to achieve than...

Beyond the Pale--Hyperion Imaging Spectrometer - It's not so much that the Hyperion instrument will be able to see the Earth more 'close up' or have a higher spatial resolution than previous instruments. Yet Hyperion's goals are nothing less than ambitious. The instrument is designed to gather highly complex data from a given region on the Earth by viewing the surface in terms of 220 distinct colors or 'bands' of light. Think of looking at a photograph in black and white and then comparing the...

Note: Traveling Dust Animation - The dust comes every year during northern Africa's dry season, when storm activity in the Sahara Desert and Sahel generate clouds of dust. The dust originating from fine particles in the arid topsoil is transported into the atmosphere by winds and may be carried in excess of 10,000 feet high into the atmosphere by easterly trade winds. Typically, it takes one to two weeks for the dust clouds to cross the Atlantic Ocean and reach the continental United States.....

This animation takes us into a spinning pulsar, with its strong magnetic field rotating along with it. Clouds of charged particles move along the field lines and their gamma-rays are beamed like a lighthouse beacon by the magnetic fields. As our line of sight moves into the beam, we see the pulsations once every rotation of the neutron star. Note: This animation shows gamma-rays from a pulsar Animator: Walt Feimer (HTSI).

This cut away of the Greenland ice sheet shows the high altitude accumulation region and the low altitude ablation (melt) zones. In a warming climate, both melting around the margins and precipitation in the interior increase, causing the ice sheet to grow in the middle and shrink at the edges.

New studies show that the Sun's active regions -- areas of intense eruptions -- are formed from many small magnetic structures (white loops) that rise from deep within the interior, then pierce the surface to form sunspots (dark areas). These structures appear as giant arches when electrified gas (plasma) passes through their magnetic fields. Note: Magnetic field lines poke through the solar surface, producing sunspots and occasionally flares. Animator: Walt Feimer (HTSI).

This illustration shows how cooler than normal tropical Pacific Ocean temperatures (blues) and warmer than normal tropical Atlantic Ocean temperatures (red and orange) contributed to a weakened low level jet stream and changed its course. The jet stream normally flows westward over the Gulf of Mexico and then turns northward pulling up moisture and dumping rain onto the Great Plains. During the 1930s, this low level jet stream weakened, carrying less moisture, and shifted further south. The...

On Friday, August 1, 2008, a total eclipse of the Sun is visible from within a narrow corridor that traverses half the Earth. The path of the Moon's umbral shadow begins in Canada and extends across northern Greenland, the Artic, central Russia, Mongolia and China. A partial eclipse is seen within the much broader path of the Moon's penumbral shadow, which includes northeastern North America, most of Europe and Asia.

This animation provides a close perspective of the relationship between ice and solar reflectivity. As glaciers, the polar caps, and icebergs (shown here) melt, less sunlight gets reflected into space. Instead, the oceans and land absorb the light, thus raising the overall temperature and adding energy to a vicious circle.

To some extent, geodesy is the study of the shape of the Earth. But it is also the study of how to find precise locations on the planet. As it relates to the study of sea level, geodesy becomes vital. The Earth is not a perfect shape and is constantly changing. Only through a very carefully constructed system of analysis can scientists achieve the necessary accuracy about the planet's shape (the so-called 'geoid') to make measurements of sea level from space. In this animation we look at how a...

GLAST's launch is scheduled for early 2008 from Cape Canaveral Air Station on Florida's eastern coast. GLAST will be carried on a Delta II Heavy launch vehicle, with 9 solid rocket boosters. The solids are actually from the Delta III series (hence the term 'heavy'), mounted on a Delta II. It has a 10-foot fairing and two stages. Stowed in the launch vehicle, the spacecraft is 9.2 feet (2.8 meters) high by 8.2 feet (2.5 meters) in diameter. Once deployed, GLAST becomes a little bit taller and...

Black soot may contribute to melting glaciers and other ice on the planet and eventually a warmer Earth. Traveling potentially thousands of miles from its sources on air currents, this pollution eventually settles out of the air, onto land and into the oceans. On ice and snow, it darkens normally bright surfaces. Just as a white shirt keeps a person cooler in the summer than a black shirt, the vast stretches of polar ice covering much of the planet's top and bottom reflect large amounts of...

In winter, moist air flows off the ocean and rises over the hills downwind of a coastal city, dropping its rain and snow mainly as it ascends the hills. As pollution from the city is pushed into the clouds by the hills downwind of the city, it interferes with droplet formation in the clouds as observed by NASA's satellites. The smaller cloud droplets convert more slowly into precipitation. Instead of precipitating, much of the water in the clouds evaporates, reducing the net rainfall downwind...

MEDIUM RAINDROP ANIMATION - Interestingly, the splash of a medium sized raindrop does not trap bubbles underwater and is consequently quiet, much quieter than small raindrops. The only acoustic signal from these drops is a weak impact sound as it hits the ocean surface. The following animation is first simulated as a real-time raindrop and then slowed to demonstrate how it does not make a bubble under the water.
